To aZZ'wwm t may concern.'

Be it known that I, CHARLES T. CUTLIP, a citizen of the United States ofAmerica, residing ,at Detroit, in the county of Wayne andvr State ofMichigan, have invented certain new and useful Improvements in SpringStructures, of which the following is a speciication, reference beinghad therein to the accompanying drawings.

This invention relates to upholstery spring construction and to a methodof applying the upholstery covering thereto and to an arrangement ofparts whereby the depending apron of the upholstery is held smoothly inposition during the process of application and is fastened by meanswhich give a smooth finish to the structure and obviate the use ofupholstery tacks, stitching or the like.

The invention is particularly adaptable for use with springconstructions having a wire or metal rim frame. i

The invention consists in the matters Ahereinafter sety forth and moreparticularly pointed out in the appended claims. In the drawings, Figure1 is a view of the underside of a structure that embodies features ofthe invention, partially broken away and arranged to show the vmethod ofapplication; Fig. 2 is a View in transverse section of the structure;Fig. 3 is a view`in detail showing a form of fastening strip applied toa rim frame; Fig. 4 is a view in detail of one form of holding member;Fig. 5 is a view in detail of a companion clamping strip; Fig. Gis aview in detail of a holding member showing a preferred constructionthereof; Fig. 7 is a view in detail of one form of spring, holding rimframe member; Fig. 8 is a view in detail showing the application of aclamping strip and holding member to a spring structure so as to formthe rim frame thereof; Figs. 9 and 10 are views in detail of themodifications of the holding and vclamping strips; Fig. 11 is a view indetail of a modifi be used; and Fig. 12 is a View in transverse sectionlof a completed structure.

Referring to the drawings a structure having upright body springs 1 ofconventional or standardl type that support ianl upper frame 2 isprovided witha lower rim"- frame 3 which asv a A Ll-shaped stri betweenwhose flanges the lower turns of t e body springs are gripped. rests onthe upper rim vSeat upholstery 4 smoothly over a -to smoothly enfoldstructure. A strip 13 the frame 11 as ed form of clip that may -of theapron. If rolled as indicated in Figs. 3 and 8, the rehereln lndicatedmay be of-.

frame 2 and a cover thereof depends in the usual manner to form an apron5.

The lower margin of `the apron is drawn holding strip 6 that in thepreferred form is U-shaped and is arranged and grip the base frame sideand end members. Spurs 7 are struck up at intervals from the flange ofthis strip to register and pass through openings in a companion clampingstrip 8, the spurs piercing the fabric of the cover 5 and retaining theclamping strip by being. headeddown upon the latter. As a preferredconstruction the margin of the clamping strip may havev a wire or' falsewire edge 9 and also inner lugs 10 that are bendable around the strip 6and the applied frame to hold the parts securely in position.

In order to smoothly draw the apron 5 into position a contacting frame'11 of suitable material is placedon the bottomy of the structure whereit is held in proper position by depending dowel pins 12 that engage thecorner springs or other suitable parts of the of suitable fabric such asburlap, canvas or the like is stitched to the margin of the apron andthe latter is drawn to place, the strip 13 being'tacked to indicated inFigs. 1 and 2. This forces the apron over and holds it securely on themember 6 while the clamping strip 8 is being applied, the temporarystrip 1 3 being thenripped of and the temporary frame removed.

If desired the strip 6 may be fiat as indi-i cated at 8 in Fig. 8

with ears 14C orthe like arranged to hold the body springs. Or asindicated in Fig. 11, the strip 6 may inclosel a rim wire l5 and thebase turn 16 of the body springs with a thereto.

As indicated in Figs. 94 and 10 the form and proportions of the strips 6and 8 may be varied. As a further detail of good construction it isadvisable that the margins 18 formed around the openings from which thetongues 7 turn up be slightly upbent to form a bearing which gives agoed seat to the clamping strip 8 and' insures its pinching downproperly upon the interposed fabric Vthe edge of the strip 8 be 'sultantmargin is liable tol project beyond the plane of the face of the strip'adjacent the apron and in such instance the shoulders 18 insure properhold upon the apron.

suitable clip 17 applied.

body of the upper ile As a result of this construction upholsterylmay beapplied very rapidly to a seat structure without the use of tacks orlines of stitching. The structure gives the finish to the base andreinforces the same. As indicated in Fig. 12, the construction lendsitself readily to holding asheet of suitable material that prevents theentrance of dust'into the structure. v y

rObviously, changes in the details of construction may be made withoutdeparting from the spirit of my invention and I do not care to limitmyself to any particular form or arrangement of parts.

VWhat I claim is 1. A method of applying upholstery to a springstructure having a base frame consisting in applying' a temporaryIupholstery strip to an upholstery apron, in tacking the same to thefalse frame applied to the base of the structure whereby the apron isdrawn smoothly 'over the main base frame and in clamping the apron tothe base frame by metal membersv that are held together by prongs whichpierce the apron, the temporary tacking strip and frame being thenremoved. 'I

2. The method of applying upholstery to a Spring seat structure having abase frame which consists in drawing the marginal portions of theupholstery apron smoothly over the frame and securing them temporarily,in

applylng clamping strips to the apron and frame which have holdingmembers that pierce the fabric of the apron and in clenchstrip andthrough the .apertures of the clamping strip and bent downwardly uponthe latter, and a wire edge on the outer margins of the clamping stripforming a support for the base below the plane of the spurs, portionsofthe other margin of the clamping strip being bent over the' adjacentmargins of the U-shaped strip to secure the parts together. i

In testimony whereof I affix my signature in presence of two witnesses.s v
